Patent GB-1066051-A (GB)
Title: Graft copolymers
Inventor: DUCK EDWARD WILLIAM
IPC: C08F279/02
Filed: 1963-02-19
Abstract: Graft copolymers are made which are the reaction products of a solution polymer of butadiene having a 1,2-addition structure of less than 10% and an unsaturated organic oil or derivative thereof, e.g. linseed, soya bean, olive, palm, maize, tung, cod liver, sperm and dehydrated castor oils, and oleic acid.  The copolymers are made by heating the polymer and oil together at 50-350 DEG  C., optionally in the presence of a solvent and a free radical catalyst, e.g. a peroxide.  The butadiene polymer may be polybutadiene or a copolymer of butadiene with styrene, acrylonitrile or divinyl benzene.  The products are used in coating applications, in mastic compositions of the type described in Specification 1,046,392, and as additives to rubbers and resins.

Abstract: 1,160,991. Ignition systems. JOSEPH LUCAS (INDUSTRIES) Ltd. Jan.27, 1967 [Feb. 16, 1966], No. 6749/66. Heading F1B. Spark ignition apparatus for an internalcombustion engine comprises a spark generating circuit for supplying spark-generating pulses to the plugs of the engine in turn, a trigger circuit coupled to the spark generating circuit and serving when biased by an input to permit the spark generating circuit to produce a spark producing pulse, a fixed frequency oscillator for providing the biasing input to the trigger circuit, the oscillator running continuously in use, and magnetic means driven by the engine for coupling the oscillator to the trigger circuit when a spark is required, the design of the trigger circuit being such that irrespective of engine speed only one spark is produced each time the oscillator is coupled to the trigger circuit. The oscillator may be coupled to the trigger circuit when required by way of a pick up winding 44 which is tuned to the frequency of the oscillators. The spark generating circuit includes a transistor 4 in series with-the primary winding 39 of an ignition coil 37, the transistor being turned off to produce a spark. A voltage dependent resistor 42 is connected across the collector emitter of the transistor for protection against back e. m. f. The transistor and resistor may be housed in the distributor which acts as a heat sink for the transistor. The oscillator and trigger circuit may also be housed in the distributor.

Title: A process for bleaching earthy minerals that in native deposits are stained by colouring matters that render them useless for industrial purposes
IPC: C09C1/28
Filed: 1921-03-12
Abstract: Discoloured earthy minerals such as kaolin, barytes, feldspar, bauxite, &c. are decolorized by suspending the finely divided minerals in water to which are added pieces of platinum, iron or zinc.  Sulphur dioxide is then introduced and is reduced by catalytic action to hyposulphurous acid, liberating oxygen, which renders the colouring-substances soluble in the hyposulphurous solvent.  The colouring-substances can be precipitated by lime or an alkali for use as pigments.  The sulphur dioxide may be prepared by the action of sulphuric acid on metallic copper.
